my 100% Assembly game development

Back to the transparent topic.

The suggestions given made me do a lot o research. For those interested I found this nice tuto. He gives two methods, I was using the first. the second is Marinus´ one, but he does it with a bitblt trick, to avoid the setPixels:

http://www.winprog.org/tutorial/transparency.html

I ended up using TransparentBitBlt in the current version. It´s working nicely and without much effort. the bonus is that it can stretch images too.


v818a:
=>1 Traced 2 bugs with OllyDbg, and 1 bug related to logic. Those could possibly make win10 work properly now (I hope)
ps: when killed, enemies stop flying for now (on purpose, to adjust the code)

Hope it works now

Perfect now!  :t

You can see later (here for example) that no setPixel is used to draw.

Like a charm :t

Hi HSE, thanks I´ll check that code. I followed this link but actually didn´t studied the code.

it would be cool to make a martian game based on this:
https://en.wikipedia.org/wiki/Valles_Marineris
do you plan on make game Engine able to import bitmaps as maps, a low res version as tilemap,hires version as terrain texture?

Not in the current plan DayDreamer. It's not a tilemap engine.

The good news is I got professional guys (from India!) to work on the art for the game! A friend of mine is going to do sound Fx.

If I cannot find anyone, I will do the soundtrack myself, although I'd rather stay away from the music in this project.

Doing great, man!  8)

Getting pretty close to trying my hand at a simple game, once I am up to a decent level with ASM.

Cheers LoneWolf!


As a quick update, my first post here after it's been moved to Game deve Forum:

This project is in full development!
I'm not posting anything new only because I'm changing too many things for this next build. Mostly code stuff related.

However, to tease things a bit, I'd like to show you guys the concept draft for the player's plane (the current art is solely for development):

Nice!   8)

I've been setting my game loop timings with QueryPerformanceCount, frequency, sleep granularity with TimeBeginTime etc...


The good news is that without any serious optimization (and a lot can be gained), I'm currently achieving 4 milliseconds per frame on my machine (bitblting to a 1920/1080 window size). Since I'm targeting a game running at 60 FPS (about 17 msec), I've got lots of headroom! And no memory leaks.


Not that bad for a beginner, I guess... :icon_cool:

[LordAdef]

Guys,

This is a test version. I'm doing a bunch of changes and it's quite broken as of now. Would you running it for me? It's broken, all I want is to see how it behaves on your machines.

The console is my debbuger, if you press (the top number 8, not the one in the numpad), it will output the relevante data for my test: frame rate, sleep time, and FPS.

I appreciate the help.
